Oh snap. You've taken it back old school! This sound was big back in the 90s.

Anyways:

Kathy Sledge - Heart (Revival Mix).

Judy Cheeks - As Long As You're Good To Me (Love To Infinity's Classic Paradise Club Mix)
Adeva - Thank You (Love To Infinity Remix)
Check out Love To Infinity's remixes from the 90s. They were mostly piano driven club tracks and they remixed many pop songs.

David Morales pres. The Face - Needin' U (Original Mix and Needin' U II) Both stomping piano house tracks. Also, I would definitely check out the old disco classic he sampled to make it, Rare Pleasure - Let Me Down Easy.

Satoshi Tomiie, Love To Infinity, and Roger Sanchez, David Morales (from the 90s!). What they do currently at least Satoshi and Roger S and David Morales is completely different from what they did in the 90s.
